Description

A kind of non-invasive ventilator protective pad

technical field

The utility model relates to medical equipment, in particular to a protective pad for a non-invasive ventilator.

Background technique

In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients.

However, the use of ventilators can easily cause pressure sores in patients. Pressure sores are tissue damage and necrosis caused by long-term pressure on local tissues of the body, impaired blood circulation, and lack of tissue nutrition, resulting in the loss of normal function of the skin. The nose and face of a patient using a non-invasive ventilator mask will be affected by the vertical pressure, friction and shear force of the mask. In addition, the humid and high temperature environment inside the mask makes the pressured part of the mask prone to problems such as redness, blisters, and rupture. Reduce the compliance of patients with non-invasive ventilator therapy. Studies have shown that without any protective measures, after 3 days of intermittent use of non-invasive ventilator masks, patients will develop pressure sores on the nose and face of different degrees.

In the prior art, Chinese patent CN201375744Y discloses a protective pad for a non-invasive ventilator. The protective pad is divided into upper and lower parts, the upper part is triangular, and the center of the triangular part has a triangular air vent; There is a single-layer one-way ventilation membrane in the middle of the rectangular part; the rest of the protection pad is two-layer, both of which are made of thickened cotton material. Although this protective pad solves the problem of pressure sores to a certain extent, it is not suitable for patients who use non-invasive ventilators for a long time, and the comfort of patients is reduced due to the setting of a one-way ventilation membrane.

Therefore developing a kind of protective pad for non-invasive ventilator is an important research content in the technical field.

The material of the triangular body 1 is divided into three layers, the middle layer is a polymer material layer 1a, and the middle layer is covered by an upper layer 1b and a lower layer 1c, wherein the materials of the upper layer 1b and the lower layer 1c are polyester semipermeable membrane layers; The pore size of the polyester semipermeable membrane is 0.01-0.5 μm; the thickness of the triangular body is 0.2-3 mm.

Preferably, the widths of the first wide band part, the second wide band part and the third wide band part are all the same, 3 cm.

Preferably, the pore size of the polyester semipermeable membrane is 0.3-0.4 μm.

Preferably, the thickness of the triangular body is 1-2mm.

The utility model has outstanding technical effects and has the following advantages.

(1) The body material of the utility model is made of foamed polymer material, and the surface is covered with a polyester semi-permeable membrane, which can not only isolate dust and microorganisms in the environment, but also has a fast and powerful absorption capacity for seepage, which can reduce Skin-impregnated, absorbent even under pressure.

(2) The utility model provides decompression protection to the patient's vulnerable parts (including: bridge of the nose, face, jaw, and forehead), wherein the hollow part exposes the patient's mouth and nose, which does not affect the non-invasiveness while avoiding skin pressure normal use of the ventilator.

(3), the utility model can ensure that the edge of the protective pad is wider than the mask, can maintain its integrity and the comfort of the patient, relieve the pain of the patient, reduce the infection rate, and reduce the incidence of pressure sores of the patient.

(4) The utility model can be tailored on the basis of the protective pad according to different types of masks and the face shape of the patient, thereby improving the work efficiency of the clinical medical staff.
